Minor MLB Transactions: 1-21-16

The Giants and veteran catcher George Kottaras are in agreement on a minor league deal with an invite to Major League Spring Training, reports Jon Heyman (via Twitter). The 32-year-old has a history of hitting for power and drawing walks, as evidenced by his lifetime .215/.326/.411 hitter in the Majors. However, he also strikes out at nearly a 24 percent clip and struggles to throw out runners. He’ll be a depth piece in San Francisco, where Buster Posey and Andrew Susac are ahead of him on the depth chart.

Fellow catcher Dan Butler is returning to the Red Sox organization on a minor league deal with a big league Spring Training invite, Heyman also tweets. Boston traded Butler to the Nationals just over one year ago, but he was released at season’s end after hitting .227/.316/.316 at Triple-A Syracuse. Butler received a brief promotion with the 2014 BoSox but has spent much of his career at Triple-A, where he’s a career .242/.325/.386 hitter in 1064 plate appearances.

The Marlins announced that they’ve outrighted first baseman/left fielder Tommy Medica to Triple-A New Orleans. Medica, 27, was designated for assignment earlier this month after being passed up on the depth chart by free-agent signee Chris Johnson. He batted .246/.308/.417 for the 2013-14 Padres but spent the 2015 season at New Orleans, where he hit .259/.314/.364 in 363 trips to the plate.

The D-backs announced that they have outrighted hard-throwing right-hander Matt Stites to Triple-A Reno following last week’s DFA. Stites, 25, was the key piece that the D-backs received in their 2013 trade that sent Ian Kennedy to San Diego, but he’s struggled with his control in both the Majors and minors. He’ll hope for better results in what will be his third stint at Triple-A. (The first two, it should be noted, have been rather brief in nature.)
